Description

Technical Field

[0001] The utility model relates to the technical field of gear shaft processing and manufacturing, in particular to a gear shaft lengthening structure and a gear inspection machine. Background Art

[0002] Before the gear shaft is tested for color matching on the gear inspection machine, it is necessary to correctly install the gear shaft on the driving box of the gear inspection machine, and then adjust and align the gear shaft with a gauge to achieve the part state required by the test. The driving box is a rotating component with clamping parts at both ends. When installing the gear shaft, the gear shaft needs to be placed in the driving box and the two clamping parts are used to clamp the two ends of the gear shaft respectively. During the test, the gear shaft rotates with the driving box; however, for a gear shaft with a shorter total length, only one end can be clamped and the other end cannot be clamped, so the gear shaft cannot be aligned, and of course, the color matching test cannot be performed. Utility Model Content

[0003] The first purpose of the utility model is to provide a gear shaft lengthening structure to address the problem in the prior art that for a gear shaft with a shorter total length, both ends cannot be clamped on a gear inspection machine, resulting in the inability to perform a coloring inspection test; the second purpose of the utility model is to provide a gear inspection machine.

[0004] In order to achieve the above first purpose, the technical solution adopted by the utility model is:

[0005] A gear shaft extension structure comprises a gear shaft and an extension shaft, wherein one end of the gear shaft is a connecting end, one end of the extension shaft is provided with an inner stop, the connecting end cooperates with the inner stop for positioning, and the extension shaft is detachably fixedly connected to the connecting end.

[0006] The utility model adopts the above-mentioned technical solution. By connecting the extension shaft to the connecting end of the gear shaft, the two clamping parts of the gear inspection machine can be clamped on the gear shaft and the extension shaft respectively, and the connecting end of the gear shaft cooperates with the inner stop of the extension shaft for positioning, so that the gear shaft and the extension shaft can be quickly positioned when connected without the need for additional alignment. Compared with the prior art, it is impossible to clamp both ends of a gear shaft with a shorter total length on the gear inspection machine, resulting in the problem that the color matching test cannot be performed. The utility model connects the extension shaft to one end of the shorter gear shaft, and then both ends can be clamped on the gear inspection machine, so that subsequent color matching tests can be performed.

[0007] Furthermore, the extended shaft includes a transition sleeve and an extended shaft body, and the inner stop is arranged at one end of the transition sleeve; the two ends of the transition sleeve are respectively detachably fixedly connected to the gear shaft and the extended shaft body; an extended shaft body and several different transition sleeves can be provided, and when facing gear shaft parts with different shaft neck sizes, it is only necessary to replace different transition sleeves without replacing the entire part, which is convenient to operate and saves time and effort.

[0008] Furthermore, the adjacent ends of the transition sleeve and the extension shaft body are positioned by means of stoppers, so that the transition sleeve and the extension shaft body can be quickly positioned when connected without the need for additional alignment.

[0009] Furthermore, the transition sleeve is connected to the gear shaft through a first bolt; a first screw hole is provided on the end face of the connecting end, and a countersunk hole is provided on the end face of the transition sleeve away from the gear shaft. The first bolt passes through the countersunk hole and cooperates with the first screw hole, and the head of the first bolt is located in the countersunk hole; the two are connected by the first bolt, the connection is firm and easy to disassemble, and the head of the first bolt is located in the countersunk hole to avoid interference with the extension shaft body.

[0010] Furthermore, the transition sleeve is connected to the extended shaft body by a second bolt; a connecting plate is provided on one end of the extended shaft body close to the transition sleeve, a through hole is provided on the connecting plate, and a second screw hole is provided on the transition sleeve, and the second bolt passes through the through hole and cooperates with the second screw hole; the two are connected by the second bolt, the connection is firm and easy to disassemble.

[0011] To achieve the second purpose, the utility model adopts the following technical solutions:

[0012] A gear inspection machine comprises an active box and two clamping parts installed on the active box, the two clamping parts are respectively used to clamp the gear shaft and the extension shaft of the gear shaft extension structure; any of the clamping parts is a plurality of adjusting bolts arranged at intervals along the circumferential direction, any of the adjusting bolts is arranged radially with its rod facing inward, and its position in the radial direction can be adjusted by screwing the adjusting bolt.

[0013] In order to improve the efficiency of assembling the gear shaft and the extension shaft, and to prevent the extension shaft from wearing the gear shaft surface, the radial fitting clearance between the inner stop of the extension shaft and the gear shaft can be appropriately enlarged. However, such a setting may cause the center lines of the gear shaft and the extension shaft to be parallel to each other and not colinear. By providing a gear inspection machine including the above-mentioned clamping structure, the gear shaft extension structure can still be firmly clamped to ensure subsequent coloring inspection tests.

[0014] The beneficial effects of the utility model are as follows: by connecting an extension shaft to one end of a shorter gear shaft, both ends can be clamped on a gear inspection machine, so that subsequent coloring inspection tests can be performed; an extension shaft body and several different transition sleeves can be provided, and when facing gear shaft parts with different shaft neck sizes, only different transition sleeves need to be replaced without replacing the entire gear shaft, which is convenient to operate and saves time and effort; by providing the gear inspection machine, the radial fitting clearance between the inner stop of the extension shaft and the gear shaft can be appropriately enlarged, thereby improving the efficiency of assembling the gear shaft and the extension shaft, and preventing the extension shaft from wearing the surface of the gear shaft.
